Abstract

In each of the cells (6) that constitute an battery module (1), a plurality of positive electrode plates (18) and negative electrode plates (19) are layered parallel to the long lateral walls of prismatic cell cases (3) with intervening separators (20) therebetween, wherein lateral edge portions of the positive electrode plates protrude beyond the negative electrode plates on one side, and lateral edge portions of the negative electrode plates protrude beyond the group of positive electrode plates on the opposite side, the protruding portions forming lead portions (18a, 19a).
